NVIDIA GeForce GT 640M LE technical specs and benchmarks

NVIDIA GeForce GT 640M LE

Summary

NVIDIA started GeForce GT 640M LE sales 4 May 2012 at a recommended price of 849.99 USD. This is a Fermi architecture notebook card based on 40 nm manufacturing process and primarily aimed at office use. 2 GB of DDR3\DDR5 memory clocked at 3.14 GHz are supplied, and together with 128bit memory interface this creates a bandwidth of Up to 28.8 GB/s.

Compatibility-wise, this is card attached via PCIe 2.0 x16 interface. Its power consumption is at 32 Watt.

It provides poor gaming and benchmark performance at 3.72 percent of a leader's which is AMD Radeon R9 390 X2.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
